SPOOL-HOLDER.

To aZZ w ham it may concern:

Be it known that I, LOUIS Penman, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Spool-Holders, of which the following is a specification.

This invention relates to spool holders, and has for its principal object to provide a spool holder of simple and inexpensive construction for supporting a plurality of spools of thread having means for locking the spools thereon.

Another object of the invention is to provide a spool holder which supports a spool of thread in a stationary position and the thread unwinds therefrom by being drawn ofi the end.

A further object of the invention is to provide a spool holder of said character having means for guiding the thread off the end of the spool.

lVith the above and other objects in view as will be readily appreciated, the invention will be hereinafter fully described as illustrated in the accompanying drawings, and the novel features thereof will be distinctly pointed out in the appended claims.

In the several views of the drawings, like characters of reference are used to designate corresponding parts.

Fig. 2 is a front view of the same,

Fig. 3 is a rear view,

'Fig. 4 is a side view of a spool supporting P Fig. 5 is a rear end view of Fig. 4,

Fig. 6 is a sectional view of Fig. 4 taken on line 6-6,

Fig. 7 is a front end view of Fig. 4,

Fig. 8 is a sectional view taken on line 88 of Fig. 9.

Fig. 9 is a view with the rear frame plate removed, the locking plate being in its upper or unlocking position,

Fig. 10 is a similar view, the locking plate being in its lower or locking position, and

Fig. 11 illustrates the key for actuating the locking plate.-

Referring to the drawings, 1 represents a base supporting a vertical rod 2, to which is fixed a transverse head 3, having its ends slotted at 4 for receiving the feet 5 and 6 of a hollow rectangular frame 7. The sides Specification of Letters Patent. Patented Dec 28 1920..

Application filed July 26, 1919.

Serial No. 313,453.

of said frame are closed by front and rear plates 8 and 9, which are provided with a plurality of alining circular openings 10 and 11 for receiving the round ends 12 of the spool supporting pins 13. As the feet 5 and 6 fit into the slots 4, the frame may be removed for more conveniently placingthe spool supporting pins therein. Arranged within the hollow. frame 7 and slidably mounted therein is a locking plate 14, which 1s provided with openings 15 corresponding to the openings 10 and 11, and adapted to aline therewith when said plate is in its upper or unlocking position. Extending upwardly from the openings 15 are tapering recesses 16, which are adapted to slide over corresponding tapering parts 17 of the spool supporting pins 13, when the locking plate is moved to its lower or locking position.

The locking plate 14 is held in its upper or lower positions by means of a channel shaped latch member 18, and said plate is out out at 19 for accommodating the latch member and for permitting sliding movement of the plate. The inner edge of the frame 7 is provided with grooves 20 and 21 for receiving the ends 22 and 23 of the latch member 18. and the edge of the locking plate is provided with grooves 24-25 and 2627, which are adapted to receive the ends 28 and 29 of said latch member. A suitable spring 30 tends to force the .ends 28 and 29 of the latch member into the grooves 2425 or 2627. As the ends 22 and 23 of the latch member fit into the grooves 20 and 21, and its other ends 28 and 29 fit into the grooves 24 and 25. the locking plate 14 is held against movement. The grooves 20 and 21 are of suflicient depth to permit the ends 22 and 23 of the latch member to slide therein, when its other ends 28 and 29 are forced out of the grooves 24-25 or 26-27 to allow the locking plate 14 to be moved. For forcing the latch member 18 againstthe action of the spring 30 to release the locking plate and then actuate the same, a suitable key 31 is employed. Said key is inserted into a key-way 32 in the rear plate 9, and its fang 33, entering a suitable recess 34 in the looking plate, is adapted to engage the rounded end of a push pin 35, when the key is turned,

member release the locking plate, and then engage the lower curved edge 36 of the re cess 34 for actuating the locking plate to its locking position. When the locking plate 'and by forcing said pin against the latch has thus been moved, as shown in Fig. 9, the tapering recesses 16 of the locking plate 14 engage the tapering parts 17 of the spool supporting pins 13, thereby locking them in position, and the ends 24- and 25 of the latch member 18 now enter the grooves 26 and 27, thereby locking the locking plate in its down position. To actuate the locking plate 14 to its upper or unlocking position for releasing the spool supporting pins 18, the key 31 is turned counter clockwise so that its fang 33 first engages the push pin 35 and then the upper curved edge 37 of the recess 84.

Each spool supporting pin 13 is square in cross section and of such a size at 38, that when a spool of thread, indicated by 39, is forced thereon over the end 12, its square corners will become embedded in the spool and thus fix it thereto. As said part of the spool supporting pin is square, its corners form a shoulder at 40 and limit the distance its end 12 can be inserted in the openings 10 and 11. The thread 41 is drawn endwise from the stationary spool 89, and in order that it may unwind properly therefrom, a disk 42 of greater diameter than the end of the spool is fixed to the pin 13 and the unwinding thread passes over its periphery as it is drawn through an aperture 43 in a guide 44. Each aperture 43 is directly opposite the end of a spool supporting pin so that the thread will unwind evenly from the end of the spool. The guide 44 is supported from the transverse head 3, to which it is fixed at 45. Whenever the thread 41 from any spool is not being used, its loose end may be attached under a spring 46, which is fastened at 47 to the projecting end 48 of each spool supporting pin.

From the description and accompanying drawings, it is apparent that, a plurality of spools of thread may be locked in aframe, that the spools will remain stationary and the thread may be drawn endwise therefrom.

Having fully described my invention, what I claim is:

1. In a spool holder, the combination of a frame, pins, the frame being provided with openings for receiving the pins, the pins being reduced to form a pair of shoulders, a plate slidably supported by the frame, and the plate being provided with recesses for cooperating with the reduced portion of said pins when moved to retain the pins in said openings of the frame, substantially as described.

2. In a spool holder, the combination of a frame, pins, the frame being provided with openings for receiving the pins, the pins being reduced to form a tapering portion between a pair of shoulders, a plate slidably supported by the frame, and the plate be ing provided with tapering recesses for cooperating with the reduced portion of said pins when moved to retain the pins in said openings of the frame, substantially as described.

3. In a spool holder, the combination of a hollow frame, pins, the sides of the frame being provided with alining openings for receiving the pins, a sliding plate within the frame, and the plate having recesses for cooperating with the pins when moved to retain them in the openings in the sides of the frame, substantially as described.

4. In a spool holder, the combination of a hollow frame, pins, the sides of the frame being provided with alining openings for receiving the pins, a sliding plate within the frame, a latch for locking said plate against movement, and means for operating the latch and for actuating the plate, substantially as described.

5. In a spool holder, the combination of a hollow frame, pins, the sides of the frame being provided with alining openings for receiving the pins, a sliding plate within the frame, a latch, said plate being provided with a recess for the latch, the latch being adapted to engage said frame and said plate to lock the plate against movement, and means for operating said latch to disengage it from said plate and for actuating the plate, substantially as described.
